Prince Harry makes his heart beat after joining Royal Marines at Mountbatten Festival of Music

Prince Harry put hearts to the party by attending the Mountbatten Music Festival tonight to watch the Royal Marines bands perform a moving performance while raising funds for the charity of the unit.

The Duke of Susbad, who held the position of Captain General of the Royal Marines, donned his finest sailor outfit and rose to join a powerful rendition of God Save the Queen at the Royal Albert Hall ceremony.

Photos of Prince Harry in his navy costume were shared on social media, with many fans expressing their admiration for the look.

The appearance of the prince was somewhat surprising, Kensington's palace announcing its presence only a few hours before the event.

Prince Harry was the guest of honor at the two-hour musical show, which also marked the 75th anniversary of D-Day.

All proceeds from the event will go to the Royal Marines Charity and CLIC Sargent.

More than 200 musicians went on stage to play in the night.

Another commented: "The Duke of Susbad is superb in his uniform."

While a third was simply saying, "Duke of hotness".

The appearance of Prince Harry comes just two days after his participation in a London event on mental health.

The Duke of Susbad appeared in an excellent state of mind as he arrived at the event with a broad smile.

The Royal Conference stressed the need for a "multi-agency approach" to address mental health issues in Britain at a conference in front of a group of academics on the conference, which was aimed to address the mental health issues of veterans.
